:) That is an excellent question. The obvious philosphical answer is, "never", but I'm not quite comfortable with that. When your interests do no harm? There's a whole other can of worms there, with the definition of "harm". It's a difficult process... Perhaps it reduces to aptitude. If I, knowing myself, my limitations and my aptitude, am able to help someone, my morality tells me that I should. As a corollary, I need to always be self-reflecting, refining my aptitude so that I am able to help others.

But, I suppose I should ask you the same. When [i]do[/i] your interests supercede others?
